Standard Test Methods for Elastic and Shear Properties
A fundamental requirement for efficient use of timber-based composite structures like glulam beams is an accurate knowledge of their mechanical behavior and the material properties characterizing that behavior. Determining the elastic properties, such as the modulus of elasticity and shear modulus, for glulam beams requires careful experimentation and can be challengeable due to the anisotropic nature of wood. Determining these properties is not as simple and straightforward as in isotropic materials. Shear tests, such as torsion and shear field and compression loading tests, are commonly employed to determine the shear modulus of glulam beams. To determine the modulus of elasticity, experimental methods such as bending and compression tests are commonly used. In this chapter, we will discuss the experimental methods commonly used to determine the modulus of elasticity and shear modulus, for timber-based composite structures. These properties are crucial for understanding the structural behavior and design of these materials. This chapter describes the commonly used methods, bending tests, torsion tests, and compression loading tests, in determining their values. To obtain accurate and reliable results, it is essential to conduct these experimental methods following established standards and carefully controlling the test conditions, specimen preparation, loading configurations, and measurement techniques.
